Risk-based closure evaluates site environmental conditions and area sensitive receptors to determine if an alternative to strict numerical regulatory closure standards would be appropriate. Considerations for risk-based closure include:
Future site use
Property use restrictions
Area property use (industrial, commercial, residential)
Soil, groundwater, surface water, and indoor air exposure pathways
Groundwater impact trends
Antea Group has decades of experience evaluating environmental risk, and our multi-disciplined teams have deep regulator and state-specific knowledge (including states with formal risk or tiered approaches, including Delaware, Maryland, Washington DC, Iowa, Alabama, and California.) When combined with our air, soil, and groundwater risk evaluation expertise and our data visualization capabilities, that's a combination you can't beat.
Our Risk-Based Closure Services
Utilizing a combination of state-specific alternative standards and national guidance documents (ASTM, ITRC), risk-based closure evaluates site environmental risk relative to area-wide receptor sensitivity. Typical risk pathways incorporate one or more of the following:
